NUT-LOCK SPECIFICATION forming part of Letters `Patent No. 652,529, dated June 26, 1900.. Application filed September 19,18'99. Serial No. 730,969. (No model.)

and useful Improvement in Nut-Locks, of

which the'following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whichio Figure l is a longitudinal sectional view showing myimproved nut-lock, the parts beingin a partially-uniocked position. Fig. 2 is a like view, the parts being in a locked posi-l tion. Fig. 3i`safront view ofthe nut. Fig. 4 i5 is a cross-sectional view on the line X X of Fig. 1, the parts being in an unlocked position. Fig. 5 is a like view on the line y 1/ of Fig. 2, the parts being in a locked position. Fig. 6 is a side view of the nut. Fig. 7 is a 2o plan view of the saine.V Fig. 8 is an interior side view of one of the sections of the nut, and

Fig. 9 is a view of the ring that holds the nut` sections together. Fig. l() is a rear view of a modified form of nut.

Like symbols of reference indicate like parts wherever they occur.

In the drawings represents the bolt,screw threaded in the ordinary manner. Fitting over the bolt is the washer 3, having the hexagonal shoulder Il, which washer, instead of being a true an'nulus on its inner circumference, is provided with one or more cam-surfaces 5, the inner sides of the washer being parallel with the bolt, and at its month with two or more beveled faces 6. The nut 7 is preferably formed intwo or more sections on longitudinal lines, which sections maybe held together by a split ring 8, which fits in a recess 9 in the neck of the nut. This neck lO of the nut is reduced in its outer circumference to be inserted 4within the inner circumference of the washer 3 and is provided with one or more cam-surfaces 1l to correspond with and be adapted to bind the cam-faces 5 of the inner circumference of the washer, and

at the shoulder of the nut it is provided with two or more beveled projections l2, adapted to engage with and bindin and distort the beveled surfaces 6 at the mouth of the washer 8.

The outer portion of the inner circumference of the nut is provided with a screw-thread;

but the inner circumference 0f the springn eeklO of the nut has a smooth surface.

Be it known that I, ANDREW V. BRYCE, of' Allegheny, in the county of Allegheny and State of Pennsylvania, have invented a new a second lock.

The outer face of this neck l0 is slotted at 13 to render it flexible and compressible.

' The operationis as follows: Theseveral sections of the nut being held together by the open ring S, the washer 3 is placed over the bolt 2 and the nut is screwed down on the bolt against the Washer, the neck ofthe nut en- 6o tering the inner circumference of the washer. When the projections l2 come in contact with the beveled faces G, the separable sections of the nut are caused to bind on the bolt, producing the first lock. The sections of the nut are held in proper relation to each other by a projection let in one section fitting in a recess l5 in another section, and the bases of these projections and recesses are beveled, as'at 16.

As the nut locks, this bevel tends to throw7 the 7o sections askew and causes them to bind firmly on the screw-thread of the bolt, thusforming The third lock is caused by turning the washer 3 on the neck l0 of the nut,

which brings the cam-surfaces 5 and 1l in 75 binding contact and presses or jams the iiexible and coinpressible neck of the nut tightly on the thread of the bolt. The inner face of the washer 3 is provided with ribs 17, that tend to keep the washer from turning. It should 8o be noted that the bore or inner circumference of the nut and washer is parallel with the bolt and not tapered,the cam-surfaces being transverse to theaxis, which enables the part-s to be formed by drop-forging. 8 5

The advantages of my invention will be apparent to those skilled in the art. Instead of forming the nut in sections it may be slotIn ted, as shown in Fig. 10, and Idesire to cover this construction by the term nut formed 9o in sections as lused in the claims.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a nnt-lock,the combination of a washer having beveled surfaces at its mouth, and a nut formed in separate longitudinally-divided sections and provided with projections adapted to engage with the beveled surfaces at the mouth of the washer; substantially as de roo scribed.

2. In a nut lock, the combination of a Washer, having an enlarged cavity with beveled surfaces at the mouth of the cavity, and

a nut formed in separate longitudinally-divided sections having a neck adapted to be inclosed Within the cavity of the Washer, and having projections adapted to engage with the beveled surfaces at the mouth of the Washer; substantially as described.

3. In a nut-1ock,the combination of a Washer having an enlarged cavity, one or more longitudinal cam -faces, and a nut formed in separate longitudinally-divided sections havinga neck with one or more longitudinal camsurfaces; substantially as described.

4. In a nut-lock,the combination of a Washer having exterior Wrench-faces and an enlarged inner cavity provided with one or more camfaces, and a threaded nut formed in separate longitudinally-divided sections and having a neck provided with one or more cam-faces adapted to coact with the cam-faces of the Washer; substantially. as described.

5. In a nut-lock, the combination of a bolt,.

a washer having an enlarged cavity provided with one or more cam-faces, a nut formed in sections and having a neck which is transversely slotted and is provided with one or more cam-faces: substantially as described.

6. In a nut-lock,the combination of a Washer having a beveled surface at its mouth, and a nut formed in sections provided with a projection and a recess at the meeting surfaces, said projection and recess being beveled at their base, and a projection adapted to engage with the bevel at the month of the Washer: substantially as described.

7. In a nut-lock,the combination of a Washer having exterior Wrench-faces and an enlarged cavity with cani-faces, and a threaded nut having a compressible neck portion with cam- -faces arranged to fit in the Washer-cavity;

substantially as described.

8. In a nut-lock, the combination of a nut formed in longitudinally divided sections provided With a projection and recess at the meeting surfaces, said projection and recess being beveled at their base and a clampingannulus for the nut; substantially as described.

9. In a nut-lock, the combination of a nut formed in sections and provided with a ring to hold the sections together and a clamping-annulus for the section; substantially as described.

l0. In a nut-lock, a Washer having an enlarged Unthreaded cavity With interior ribshaped cams parallel .with the bolt, said Washer having beveled faces at its mouth, and a nuthaving acompressible neck-section with cam-faces arranged to enter the Washer, and provided with a bevel-face to engage the bevel-face of the washer; substantially as described.

Il. In a nut-lock, awasherhaving exterior Wrench-faces and provided With an extension having` an enlarged eccentric cavity, and a beveled face at its mouth, and an internally-threaded nut having a neck arranged to fit in the cavity ot' the Washer, and provided With beveled faces, substantially as described.

12. In a nut-lock, a Washer having exterior wrench-faces and interior cam-faces, and a nut made in separate longitudinally-divided sections having engaging projections and recesses attheir meeting surfaces, said nut having a compressible extension provided with camfaces engaging the cam -faces of the washer; substantially as described.

In testimony whereof I have hereunto set my hand.
